田口穩健設計方法於甩炮產品品質改善分析

Abstract

中文摘要 本研究旨在使用田口方法實驗甩炮在不同製程條件下之性能（音量分貝之大小），並分析其在不同品質製程之適用性及應用價值。透過結合課堂所學及參數設計流程，設計一系列實驗並量測數據，探討甩炮在摺法、紙張種類、紙張尺寸、施力位置各方面表現，並根據Minitab直交表製作不同製程參數的甩炮並依據音量分貝大小進行比較。 研究結果顯示，紙張厚度與尺寸為影響甩炮聲響（以分貝計）之重要因素。經分析可得知，採用較輕薄且面積大之紙張，能有效提升甩炮所產生之聲響分貝數，具有更好的應用性。本研究利用田口方法 (Taguchi Method) 進行參數設計，藉由系統化之S/N因子反應分析，確認紙張種類及紙張尺寸為顯著影響聲響之關鍵控制因子，並於後續確認實驗中進一步驗證之有效性與可靠性。研究同時證實田口方法能於有限次數之實驗條件下，準確找出最佳之甩炮製程參數組合，凸顯此方法於產品品質改善與參數最佳化之實務價值。

Abstract This study aims to use the Taguchi method to test the performance (volume in decibels) of the firecracker under different process conditions, and to analyze its applicability and application value in different quality processes. By combining what we have learned in class with the parametric design process, we designed a series of experiments and measured data to explore the performance of firecrackers in terms of folding methods, paper types, paper sizes, and force application locations. We also made firecrackers with different process parameters based on Minitab orthogonal tables and compared them based on the decibel level. The research results show that paper thickness and size are important factors affecting the sound of firecrackers (measured in decibels). After analysis, it can be found that using lighter, thinner and larger paper can effectively increase the decibel level of the sound produced by the firecrackers and has better applicability. This study used the Taguchi Method for parameter design. Through systematic S/N factor response analysis, it was confirmed that paper type and paper size are key control factors that significantly affect sound. The effectiveness and reliability were further verified in subsequent confirmation experiments. The study also confirmed that the Taguchi method can accurately find the best combination of blasting process parameters under a limited number of experimental conditions, highlighting the practical value of this method in improving product quality and optimizing parameters.
